Sending the config is not enough, since I can not use it in my server, I 
do not have your kind of traffic. The config is good when is some 
misrouting or syntax error, but for this specific case the 
investiagation of core and adding some patches to print more information 
when the crash is happening is the way to solve.

I sent you some patches, that were not good enough because I had no 1.5 
around and I was offline. More than that, I can count 3-4 more 
developers that tried to help you on the public mailing list, even you 
play with very old versions. As said, everyone tries to do it in 
available time and its own conditions.

I would need access to the server to investigate the core dump myself -- 
you offered that but being traveling was not for me at that time. My 
interest is to discover if it something that affects 3.x, although we 
changed the internal architecture a lot, might be some cases existing in 
1.x still applying in 3.x

What I don't understand is the complain regarding testing. When you did 
the upgrade to 1.5 from 1.3, you had to do changes everywhere, there 
were major versions. Same would be for a migration from 1.5 to 3.1. You 
can even have them both installed, using shared database so you can 
start/restart with older or newer versions. I did it many times and it 
goes smooth, just few tables have changed the structure, for that case 
you can use different databases.

Cheers,
Daniel
